Unable to make jetson-inference on Ubuntu 18.04 host

Hi,

I had install JetPack 4.2 and TensorRT 5.1.5, as well as cuDNN 7.6.1 on Ubuntu 18.04 host. I followed the instruction of building the project from source from jetson-inference/building-repo-2.md at master · dusty-nv/jetson-inference · GitHub and completed the step of cmake …/. Now, when I run the next step of make command, error is shown as below:

nvidia@nvidia-host:~/jetson-inference/build$ make
[ 1%] Linking CXX shared library …/x86_64/lib/libjetson-utils.so
/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status

make[1]: *** [utils/CMakeFiles/jetson-utils.dir/all] Error 2

make: *** [all] Error 2

I check libGl using command ‘dpkg -l | grep libgl’ and results are shown as below:

Finally, I check the libGL using command ‘ls -ll /usr/lib/aarch64-linux-gnu/libGL.so*’ and libGL.so* is missing:

ls: cannot access ‘/usr/lib/aarch64-linux-gnu/libGL.so*’: No such file or directory

Should I make symbolic link for them and where do I link to?
Please help me to solve this problem. Thanks!

Hi Raymond, jetson-inference isn’t tested against building on desktop, as it’s meant to be built on the Jetson. /usr/lib/aarch64-linux-gnu/ is the library path on aarch64 (arm64), so x64_64 will need another path. You can find the location of your libGL with this command:

$ find /usr -name "*libGL.so*"

Then you will want to add this path as a link_directory() in CMakeLists.txt

Thanks to dusty_nv.

However, it doesn’t work for me. I use find command and libGL.so are found in /usr/lib/x86_64-linux-gnu/. I add “link_directories(/usr/lib/x86_64-linux-gnu/)” in all CMakeLists.txt files in /home/user/jetson-inference/.

I have complete the building jetson-inference using the bellow symbolic link commands:

sudo ln -s /usr/lib/x86_64-linux-gnu/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so
sudo ln -s /usr/lib/x86_64-linux-gun/glib-2.0/include/glibconfig.h /usr/include/glibconfig.h

After make install, the x86_64 directory structure is built.
